  • Patent number: 7267952
    Abstract: The present invention provides a method of extracting virus genes, which is excellent in quickness and convenience and can be automated, and this invention also provides an apparatus for such extraction of virus genes. A conductive hollow fiber membrane (module) 12 is immersed in a virus suspension 20 and thus viral particles suspended in the virus suspension 20 are captured in the conductive hollow fiber membrane (module) 12. The coating of the thus captured virus is lysed and the virus genes are released. Next, the virus genes are collected by subjecting the conductive hollow fiber membrane (module) 12 to at least one of an electrical treatment and a physical treatment.

  • Patent number: 6938419
    Abstract: A control apparatus for an internal combustion engine which is mounted in a vehicle and has a supercharger that is located along an intake passage of the internal combustion engine and driven by a motor, includes a controller which drives the motor to perform supercharging during warm-up of the internal combustion engine, and supercharges a plurality of times intake air to be supplied to the internal combustion engine. Accordingly, the intake air is supercharged a plurality of times during warm-up of the internal combustion engine, so the temperature of the intake air is raised sufficiently to warm up the engine, thus enabling the engine to be warmed up effectively.

  • Patent number: 6865782
    Abstract: A slide fastener in which an insert pin and a box pin of a separable bottom stop assembly made of synthetic resin are molded integrally along side edges of fastener tapes. The insert pin and the box pin have peripheral shapes allowing themselves to be inserted into element row guide grooves of a slider, and are molded integrally such that the entire insert pin and the box pin incline toward rear face sides of the respective tapes from their inner side edges to outer side edges relative to tape planes of the fastener, said rear face sides having no core threads of the core portions. Thus, resin layers having substantially even thickness can be formed on both the front and rear face sides of the core portions so that the resin layers never peel away from rear surfaces of the fastener tapes, and the core portions and their peripheries never become brittle.

  • Patent number: 6851162
    Abstract: A reinforcement tape is stuck to an outer front surface of a fastener tape and a fastener element removed portion at a space portion, in which fastener elements are removed and to which the separable bottom end stop of the concealed type slide fastener, for example, a insert pin or the like is attached, by ultrasonic welding. The reinforcement tape may be, for example, a tape whose front surface is made of a thermoplastic elastomer film while its rear surface is made of hot melt adhesive agent. At the same time of the above sticking, an edge portion is formed into a U shape and its surface is reinforced and then, the insert pin or the like is attached to this portion. The fastener tape itself does not come into contact with a diamond of a slider, even if outer face of the U-shaped edge portion comes into sliding contact with the diamond, so the fastener tape is protected from being worn or damaged.

  • Patent number: 6780264
    Abstract: A method for welding synthetic resin members includes the steps of detecting a temperature of a high frequency electrode or an ultrasonic horn (or an anvil) by a temperature detector, cooling the high frequency electrode or the ultrasonic horn (or the anvil) by cooling means when the temperature detected by the temperature detector during a high frequency or ultrasonic vibration exceeds a preset temperature range, thereby reducing the temperature rapidly down to the preset temperature range, and stopping an operation of the cooling means when the temperature of the high frequency electrode or the ultrasonic horn (or the anvil) is reduced to the preset temperature range.
